Swee Aun Khor 334eb3ba15 Add a new SDIO controller driver for Efinix devices ...

The driver supports UHS-I bus speed modes: SDR25, DDR50, and SDR104.
By default, the controller operates in SDR25 mode. Higher-speed modes
can be enabled via the Device Tree by adding the following properties
to the SDIO node:

  - sd-uhs-ddr50
  - sd-uhs-sdr104

When these properties are present, the driver negotiates the highest
supported UHS mode with the card and host.
